Dynos⎯You're either all talk or you know for a fact what your ride puts down. After weaving their way through the crowds, gawking at various cars and popping off the rev limiter a few times to turn heads, entrants pulled up to the garage where techs hopped into the driver’s seats and carefully backed up the cars onto the dyno. The cars are then strapped down, fans are turned on and the techs rip off three different runs. The reading is then written onto the running list of makes, models and horsepower. Typically, dynos are used for tuning tools, much like a tape measure is used for building something with precision, but they also double as fabulous competition power measurement devices. Even then, with so many variations and often inflated power readings these days, it's difficult to truly know how much power a car is capable of. Instead of comparing scurrilous dyno sheets, dyno competitions offer up an opportunity to compare real life numbers, while minimizing the variables. This leads to that unquestionable requirement for facts that are a prerequisite for a true contest.
